Son Eun-seo

At an emergency call center, workers attempt to fight crime and rescue lives using the limited information they receive from desperate callers.

Eun Yong, a money business titan and an affluent financial capitalist, has been living a life of a recluse in the pastures of Mongolia. Eun returns to Korea when his nephew Tae-chun and his late benefactor's daughter Joon-gyeong enlists his help. He prepares for war against corrupt powers to protect his beloved family and to avenge the death of a dear old friend.

What happens when blood is no longer thicker than water? When greed, betrayal and secret love affairs come into play, even the closest of family members might consider murder.

A failing crime unit and a top chief unite to become one unstoppable team.
